摘　　要：基于双折射效应和去直流检测法,建立一种磁光式电流互感器(magneto-optic current transformer,MOCT)模型.该模型在一次侧电流检测部分,采用Jones矩阵建模,综合考虑Faraday效应和磁线振双折射效应;在二次侧转换器部分,建立去直流双光路检测法分析光强度信息.数值仿真和实验验证了MOCT模型的正确性.该模型考虑了磁光式电流互感器的光学检测特性,可为MOCT应用提供理论支持.A mathematic model based on birefringence effect and deleting DC double-light detection is proposed for a magneto-optic current transformer （MOCT）. By considering the Faraday effect and magnetic linear birefrin-gence effect, the first side current detecting mathematical model is made with a Jones matrix. At the secondary converter side, the method of deleting DC double-light is proposed to meet the current measurement demands. Simulation and experimental results demonstrate the validation of the MOCT model, which provides a theoretical reference for practical MOCT applications with the consideration of MOCT detection characteristics.
